The gorgeous video, filmed at a summer camp near Big Bear Lake, California, was directed by Gabriel Younes. The mini movie features an elderly man, played by actor Harwood Gordon, coming to terms with death and gut-wrenchingly accepting life's journey as he physically and emotionally bathes in a river and buries a live-version of his soul in a freshly dug grave.

DeWyze couldn't be prouder of the end result, which he says accomplished exactly what he had been striving for. "The music and the lyrics themselves are already so emotional that when the final pieces of the video were put together and I saw it for the first time, I was blown away," he shared with ET. "It moved me, and that's what we were all hoping for."

Younes felt the same way, telling ET he didn't want to divulge too many details about the video's meaning so fans could interpret the message for themselves. "I just hope they feel it in their gut and on the back of their neck when they're done watching," he said.

Wondering why you didn't spot DeWyze in a single scene? Credit artistic merit for that decision. "I wanted this video to feel like a short movie with a score, rather than me with my guitar, and I want the audience to make of it what they make of it," he explained. "The song and the video have meant so many different things to so many people. It's kind of amazing."

While DeWyze insists all of the songs on Oil & Water -- which has a heavy focus on instrumentation supporting the lyrics and is sonically as cohesive as it is moving -- are important to him, "Stone" means the most "on many levels."

"It set a bar for the rest of the recording writing for me," he said of the song, which was one of the first he penned for the album. "When I first wrote the song, it meant many things to me on many levels -- dealing with life, death, and what you leave behind lends itself to a song like 'Stone.' It's honestly one of my favorite songs I've ever written."

The 30-year-old songwriter wrote, recorded, and produced all of Oil & Water, and he admits that "blood, sweat and tears were literally poured into this album for me."

The "Sweet Serendipity" singer rose to fame with his successful run on Idol six years ago, and he looked back fondly on his time there as the music competition show comes to an end after 15 seasons. "I will always appreciate my experience on American Idol," he said. "The experience and the fans gained from the show are priceless."
